Abstract
We present a case of infiltration of carbon debris particles in the dura after lumbar fusion with a carbon implant.
To improve understanding of the precipitation of carbon particles in the dura after lumbar fusion with a carbon implant and to determine the clinical significance of this finding.
Summary of Background Data: During the past several decades, the carbon fusion cage has been used more frequently in spinal surgery to reduce the complications of lumbar fusion and to simplify the posterior lumbar interbody fusion(PLIF) procedure with an autologous bone graft. However, few carbon implant complications related to debris particles as a result of wear, have been reported.
A patient with infiltration of carbon particles in the dura after lumbar fusion with carbon implants was reported.
Infiltration of carbon debris particles in the dura was found during the re-operation, 10 years after lumbar fusion with carbon implants. Microscopic examination showed multi-focal depositions of carbon particles without inflammatory cells surrounding them. Carbon particles were present within macrophages, suggesting that they had been phagocytosed in vivo.
Carbon cages can be broken into small pieces, resulting in infiltration into the surrounding tissue. However, there was no histologic evidence of particle-induced bone resorption or inflammation. The presence of carbon particles had no discernible adverse effects up to this time.
